Polymer Lab Group Investigation

Yesterday, we took our results from last weeks labs and came up with a lab that we wanted to do by ourselves and we decided that we would add or subtract some borax solution to the glue experiment to see what it did. I thought that if we added some Borax then the polymer would be stretchy and very bouncy. The polymer was very bouncy but did not stretch very far. The control was in the middle of the polymer that we took borax solution from. The polymer that we took the borax solution from was very stretchy but only bounced seven centimeters. While we were making the third polymer, it started to look like sour milk. For trial two (control) we used 25 milliliters of borax solution, we did that exact experiment last week but did not test the stretch. For trial two we used 35 milliliters of borax solution, it was the bounciest but did not stretch very far. For trial three we used 15 milliliters of borax solution, it did not bounce very high but it stretched 60 centimeters.
